part-1y broken away, taken along the inner wall looking a *ay from the driving side of the machine. Fig. 4 is a fragmentary sec-. tion on line H of Fig. 3. 'Fi 5 is a frag- 6 is a fragmentary section on line 6 6 of Fig. 3. Fig. 7 is a fragmentary section on line 7-7 of Fig. 3.

As shown in the drawings: 1, i dicates the scalding tank or trough. the side walls 2, of which at one end of the machitie; are extended upwardly and rearwardly to ,afford the side walls for the scraping mechanism. and suitable posts 3 and el, are provided oneach side the machine at said end to afford the framefor the mechanism mounted thereon. As shown, a relatively high perforated wall is provided in the scalding tank in advance of the scraping mechanism, and is of a height to extend wellabove the surface of the hot water in the tank. i

An inclined or cylindrically concave floor 6, of perforated material, eivtends from the top of the perforated wall 5, downwardly well below the surface of the water in the relatively small con'ipartment at the rear of the perforated wall. and then inclines upwardly to the top of the rear end wall 7, of the tank. Journaled transversely the machine on a suitable beam secured on the posts 3 and 4. is ashaft 8, and rigidly secured. thereon is a drum 9, of relatively-large. di-' ameter, provided upon its periphery with closely arranged scraping blades 10. which are'arranged thereon longitudinally of the roll. as shown in Figs. 3 and 4. and comprise metallic blades having upwardly turned ends. and which are set close together in the length of thedrum in each line thereof. Said drum is shown as of larger diameter at the ends than at the middle; in other. words, the same tapers comically inwardly from each end to a cent 7:11 cylindric portion. The floor (3, conforms to the curvature of said drum, the outer ends of said drum as shown in Figs. 8 and 4, being at a sufficient distance therefrom to afford adequate clearance for the scraping blades.

Journaled on suitable bearings supported on the side wallsof the machine in advance of the post 4, is adriving shaft 11, provided. on one end thereof with a driving belt pulley 12, and a sprocket wheel 13, and at the, other extremity is provided with a sprocket wheel 1.

14. Journaled above said shaft and in suitable bearings on the post 4:, is a shaft 15, which extends transversely the machine and rigidly secured on which is a. roller or drum 16. A s rocket, wheel is rigidly secured on said she 15, at each end of the roll 16, and adjacent each side wall of the machine.

A shaft 17, is journaled in the tank transversely; thereof near the bottom of the same, and well in advance of'the shaft 15, as shown in Figgfii and 4. A roll or drum 18, is proil ided on' said shaft, corresponding with the roll or drurri 16, on said upper shaft, and sprocl'ret wlreels are also provided at each end of saidroll or drum Corresponding with Trained about said those' pp the shaft 15.

sprocket wheels on said shafts, are carrier ch aiiis 19, having angular bars 20, which extend transversely the machine, secured to each to afford means for conveying the carcasses from the tank. As shown, transverse bars 21, extend across the tank, engaged on the sidewalls thereof, and supported thereon with the upper surface thereof substan tially at a tangent with the tops of the rolls ,16 and 18, is a perforated floor 22, over j yvhich the bars 20, slide at the upper run of the carrier. As shown, a sprocket wheel 23, .o

is provided on said shaft 15," in alinement with the sprocket wheel 13, before described, and about the same is trained a sprocket chain. whereby the conveyer is actuated directly from the main driving shaft 11.

Journaled transversely the machine at the rear of the main driving, shaft, and slightly above the same, is a shaft 24:, having: peripherally arranged scraping blades 25, thereon, and engaged therewith by means of short, stiff pieces of belting 26. Such connection between the blades and the shaft, may, however,.'be of other material to afford more or less resiliency, the object being to yicldingly engage the scraping blades on said shaft to permit the same to spring somewhat at the resistance encountered against the carcass, thus enabling the blades to conform to all parts of the surface of the carcass. As shown, a sprocket wheel 27, is provided on the end of said shaft 24, adjacent the sprocket wheel l i, on the shaft 11, and trained about said sprocket wheels, is a sprocket chain, whereby power is communicated thereto from the driving shaft 11, to rotate the same continuously and in a di-' rection to cause the scraping blades to act upwardly upon the carcass, and to permit said shaft with the scraping blades thereon, to deliver the carcasses from the upper end of the conveyer thereover to the scraping drum or roll 9.

Journaled transversely at the top of the machine atthefrontsidc thereof, is a shaft 28, as shown more fully in Fig. (l. Jodi? naled on said shaft at the inner side of me of the side wvalls, is a sprocket wheel 23 provided with an elongated hub 30, em

iruunicates the drive to the drum 9, and also to' t he sprocket wheels 31 and 29.

Rigidly secured on the shaft 28, acent the sprocket wheel 29, and adjacent the opposite side wall of the machine, are rear wardly and downwardly, directed arms 33', of a length to extend inwardly and rearwardly over and past the scraper drum 9., Near their extremities, said arms are bent downwardly, as shown in Figs. 3 and 7, affording a downward extension 34-.

Journaled at the bend between said arm 33 and extension 34, is a shaft 35, provided on each end thereof, with sprocket wheels 36 and 37 respectively. Journaled at the lower end of the extension 34, of said arms, and extending transversely the machine, is a shaft 38, having a sprocket wheel 39, thereon in alinement with the sprocket Wheel 37, above the same on the shaft Secured on said shaft 38, by means of flexible connections 39, similar to the flexible connections 26, before described, are scraping blades 40., A sprocket chain 41, is trained about the sprocket wheel 29, on the shaft 28, and about the sprocket wheel 36, on the shaft 35, and a sprocket chain 42, is trained about the sprocket wheels 37 on the shaft 35, and the sprocket wheel '39, on the shaft 38, thereby driving the shaft 38, in a direction to cause the scrapers to act inwardly and upwardly on the carcasses which arebrought against the same by the rotation of the scraping drum 9, as shown in Fig. 3.

As shown, a levdr 43, is rigidly secured on the end of the shaft 28, at the operating side of the machine, and extends into position to be easily reached by the operator, and is provided with a counterweight 4E4, adjustable thereon to partly counterbalance the weight of said arms 33, extensions 34:, and mechanism supported thereon.

As shown, the floor 6, is provided with a relatively broad transverse slot well above the water line in the tank, and in advance of the scraping rollfiind fitted therein and 6X- tending to the bottom of the tank is a tight receptacle 45, open at'the top, and the bottom 46, of which inclines latcrally -to-anr opening at the bottom of said receptacle and througlfithc side wall of thetank, as indithe drum 16, at the upper end of the conveyer over the scraper shaft 24:, and scrapers thereon, to the scraping drum 9, and are carried thereby against the scrapers on the shaft 35, which act oppositely upon the carcasses from the scrapingdrum 9, and insure the carcasses being turned transversely the machine with the head and rump supported at the raised portions of the drum. The carcasses are constantly and rapidly rotated by the eoaction of said scraping elements, and when, in the judgment of the operator, the scraping operation is completed, the operator brings the lever 13, downwardly, thereby elevating the scraping shaft sufliciently to permit the carcasses to be ejected by the scraping drum-9, onto the table at the rear end of the machine. During the entire operation, the scraping drum (the lower.,por tion of the periphery of which extends below the surface of the water in the tank) has acted to dash the water from the tank constantly over the carcasses, laving the same with hot water during thescraping operation and insuring thethorough scraping and cleansing of the carcasses. Any

, hair or material removed from the carcasses,

falls upon the floor 6, and the scraping blades carry the same forwardly and deposit the same in the receptacle 45, before described, whence such refuse slides to the discharge aperture X,and from the machine.

Of; course, it is to be understood that the particular construction of thescraping elements-may vary ,througha wide range, as.

may also the particular drive therefor, and it is to be understood that I have shown. but a preferred embodiment of my invention, and I therefore do not purpose limiting the patent granted on this application, otherwise than necessitated by the prior art.
